Abstract

The invention provides a charging method and device for an electric vehicle. The charging method is applied to a charging pile. The charging method comprises the steps that an awakening signal for awakening a vehicle control unit is sent to the vehicle control unit of the electric vehicle; when the vehicle control unit is in the awakening state according to the awakening signal, the charging pile continues to send charger handshake messages (CHM) to a battery management system (BMS) within a preset period of time, and monitors whether a BMS handshake message (BHM) fed back by the BMS according to the CHM is received or not within the preset period of time to obtain a monitoring result; according to the monitoring result, a charging national version to which the electric vehicle conforms is obtained; according to the charging national version, the electric vehicle is charged. According to the charging method and device for the electric vehicle, the problem that in the prior art, due to the fact that the charging national version to which the electric vehicle conforms cannot be recognized, the charging success rate of the electric vehicle is not high is solved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a charging method and device for electric vehicles. Background technique [0002] At present, electric vehicle charging is an important part of electric vehicle control. After China implements the new charging national standard (GB / T27930-2015) in 2016, electric vehicles that meet the new charging national standard and the old charging national standard (GB / T27930-2015) will appear on the market. / T27930-2011) electric vehicles. At this time, although the new national charging standard will take into account the charging compatibility of the old charging piles on the market that meet the old charging national standard when formulating charging standards, due to the irregularity of the old charging piles, electric vehicles that meet the new charging national standard will pass the old charging standard. The phenomenon of unsuccessful charging when charging the old charging pile o...
